MINE CAR.

Application filed April 16, 1925.

I This invention relates particularly to mine cars in which the under frame consists of side sills and end structures connecting the side sills.

The object of the invention is to provide such a car with end structures comprising pin and link couplings of a novel and convenient and strong form, an ordinary coupling pin being associated with one end structure and a coupling pin of special form and coupling links being associated with the other end structure.

As to general features, the end sill structures are similar to the end sill structures of Letters Patent, No. 1,486,547, granted to me, March 11, 1924:, for an improven'ient in railway cars.

In the accompanying drawings,

Fig. 7 is an upright section 7-7, oat Fig. 2, looking in the the arrows;

Fig. 8 is a perspective of the coupling pin shown at the left in Figs. 1, 2 and 3;

Fig. 9 is a plan showing a sheet. steel blank from which is made the body of the end sill structures;

Fig. 10 is a perspective showing said blank bent into form to become a part of either one of the end sill structures;

Fig. 11 is a perspective of one of the corner members used for joining the side sills to the body of the end sill structures;

Fig. 12 is a perspective of an anchor member; I

Fig. 18 is a perspective of a bumper mem ber;

on the line, direction of on the line, direction of Fig. let is a plan of a modification of the Serial No. 23,525.

slanting edges, 13*, and the corners of the 7 lower flanges, B are similarly cut to make slanting edges, 13 (Figs. 9 and 10). This member, B, is formed by folding the blank of Fig. 9, alon the dotted lines, B. The blank is cut iroin a plate of rolled steel of desired thickness. This member, B, is also provided with holes as will be described further on.

In the form shown in the drawings, this body member, B, is long enough to partially over-lap the adjacent ends of the side sills.'

Said body and the side sills are joined to each other by means of corner angle members, C. One of these angle members is shown in perspective in Fig. 11.

One arm or blade of the angle member rests against the outer or back flat face of the body, B, and is secured to the body member by bolts or rivets, C extending through said blade and the body. The drawings show SlX such bolts or rivets. The other arm or blade of the angle member, in the form shown by the drawings, is secured to the inner face of the upright web of the side sill. Bolts or rivets, C zitend through said blade and said web to join said parts firmly to each other. In the form shown in the drawings, six such bolts or rivets, C are used. These corner angle members and the bolts or rivets used for securing these angle members to the body, B, and the side sills, A, are to be suiticiently strong to give rigidity to the frame formed by the side sills and the end structures. The upright web, B of the body member, B, is wider than the height of the side sills, A, A, to allow making acoupling link space, as will be described further on.

In the end structure at the right in Figs. 1, 2 and 3, a second member, D, of strong wood, preferably oak, is placed on the lower flange, B and against the upright web. B of the body member, B. The upper and All 0 1,so7,5ee

the lower and the inner face of the wood member, D, are straight; while the outer face of the wood member is substantially even with the middle parts of the outer edges of the flanges, B and B of the body, i), and said face is extended outward beyond said flanges at each side of said middle parts.

Midway between the ends of each end structure the wood is cut away below the flange, B enough to make room for a coupling link.

Midway between the ends of the end sill structure at the right in Figs. 1, 2 and 3, an angle-form anchor member, D extends across the upper face of the wood member, I), and between said member and the web, B of the body, B, and is secured to said web by rivets, D (Figs. 3, 5 and 12). The horizontal part of the'anchor member has a hole, D to receive a coupling pin to be described further on. A metal bumper member, E, of U-form cross section and having an upright web, E and an upper flange, E and a lower flange, E is placed over each extension of the wood member, I), and has its web, E bearing against the outer, upright face of the wood member, D, while its upper flange, EF, rests on the upper face of the upper flange, B and its lower flange, E over-laps the lower face. of the lower flange, B of the body, B. These bumper members are to receive contact Or impact from the bumper of another car. In the form shown in the drawings, the ends of the two cars are duplicates relative to these bumper members, E, so that when said ends meet, the members, E, of one car will make contact with the members, E, of the other car. Upright binding bolts, E, extend through the flanges, B and B and the wood member, D. In the space at each side of the slot, B each of said bolts is surrounded by a spacing sleeve, E whereby the space bet-ween the wood member and the upper flange, B is maintained. These bolts, E, are near the upright web, B of the body, B. Bolts, E, extend through the flanges of the bumper members, E, and the upper flange, B and the wood member, D, and the lower flange, B

Ac coupling pin, F, extends downward through the upper flange, B and through the coupling link, F and through the anchor member, D and into the wood member, D, far enough to give said pin good seating.

Turning now to the left hand end structure of the drawings, the upright web 13 of the body, B, has midway between its ends an upright slot, 13. and the upper flange, B of the body, B, has midway between its ends a circular opening, B

On the rear face of the upright web, B is a reinforcing plate, B, which is slotted to conform to the slot, 13 This plate is to be riveted or otherwise secured to the flange, B A reinforcing plate, B is placed on the flange, B and apertured in alignment with the aperture, B

The horizontal arm of the angle-form coupling pin, F extends through the slots in the web, 13, and the reinforcing plate, 13", while the upright arm of said pin extends upward through the apertures in the flange, B and the reinforcing plate, B, which rests on said flange. The head, F, of the coupling pin is back of and bears against the reinforcing plate, 13. A nut,

F is threaded on the upper end of said pin above and rests on the upper face of the plate, B A. cotter pin, F, extends through the coupling pin immediately above said nut to prevent the latter from moving upward. Before this coupling pin is put into position, a coupling link, F is applied to the pin. The slot, B is long enough to allow the coupling pin to move downward, after the cotter and the nut have been removed, to allow the upper end of the coupling pin to pass down through the opening, 13*. On the link F is a link, F and on the latter is the link, F which, as already described, is adapted to be engaged by the coupling pin, F, of the end structure shown in the left hand part of the drawings.

When these links arefree from the coupling pin, F, and still engaged by the coupling pin F they hang over the outer edge of the lower body flange, B in the space between the extensions formed by the two wood members, D, and the metal bumper members, E. (See Fig. In this position, these links will not be hit by the end structure of an adjacent car.

And the link, F is engaged by the angleshape coupling pin, F at approximately the height of the engagement of the link, F on the coupling pin, F, in the adjoining end structure. For good operation, this is desirable.

If the ordinary straight coupling pin were used, providing for hanging the links out of range of the adjacent end structure would require removing wood above the lower flange, B and cutting an opening through that flange. 'ihereby that flange would be weakened, An anchor member like the anchor member, D, used in the adjoining end structure could not be used here; nor would any form of reinforcing at the lower flange, B a *1 il, because then there would be an increase of the length of the part of the coupling pin exposed to strain, and the coupling link, F. would hang too low relative to the coupling link. F on the adjoining end structure. That would be the case when the two cars are to be coupled to each other, and after they are lld coupled, the length, F, would tend to slide down on the straight coupling pin. In connection with what has been said, it is to be observed that in the adjoining end structure, the anchor member and the flange, B", form coupling pin bearings near each other, whereby link strain is applied to only a short part oi the coupling pin.

By extending the angle coupling pin through the upright web, B and through the reinforcing plate, B a strong engagement is made for that arm of this coupling pin. This engagement can be made still stronger by applying the inclined bottom plate, H, as indicated by Figs. 14 and 15 oi the drawings, the higher edge of that plate over-lapping a part ol the upper face of the upper flange, B of the body, B, and being suitably secured to the flange, B as by some'of the bolts which extend through the upper flange, When thus applied, said floor plate will add stability to the upper, inner part of the end structure, the part to which the angle coupling pin is secured.
